This pattern is for mathematically ideal crochet spheres of different sizes! There are 10 different sizes in this pattern. Turns out the number of stitches in each row scales with sin(theta), where theta is the polar angle of the sphere.

These are crocheted versions of the Mercury Atlas and Redstone Rockets that sent the original Mercury astronauts into space in the 1960s! These soft miniatures would be great for kids big and small who love rockets!
